The Messenger of Allah ﷺ said, "The fire that the children of Adam kindle is one part out of seventy parts of the fire of Hell."They said, "Messenger of Allah, even this fire would have been sufficient."He replied, "It has been made to exceed it by sixty-nine parts."
أن رسول الله ﷺ قال: نار بني آدم التي يوقدون جزء من سبعين جزءا من نار جهنم. فقالوا: يا رسول الله! إن كانت لكافية. قال: إنها فضلت عليها بتسعة وستين جزءا.
Malik narrated it in Kitab Jahannam (1872) from Abu Zinad, from Araj, from Abu Hurairah, and he related it. Bukhari narrated it in Bad Khalq (3265) through the route of Malik, with the same wording. Muslim narrated it in Jannah wa Sifat Naimiha wa Ahliha (2834) through another route from Abu Zinad, similarly, adding at the end, "All of it is like its heat."
